Meadow, I agree with the other perspective. Mrs. Angel Mouse makes a good point about keeping some of her cheese for her family. Mice families should share their cheese freely; little mice don't usually have a lot of cheese, so I'm sure Mrs. Angel Mouse gives lots of her leftover cheese to her little mice.
Outside of mice families, mice can just be cheese sharing friends, but I have learned that friends always break cheese together. I have a mouse friend who takes lots of my cheese--think Gus from Cinderella--but down the line, he will always offer every scrap of his cheese to me when I am a sad, cheese-less mouse. I also have mouse friends who give me their cheese regularly, knowing I may need help. But I make note of the cheese, and I always give back whatever I am able to, as a thank-you for the cheese they shared.
See, in these cheese relationships, it's one-sided for a time, but the understanding is that the giving party will always receive back some cheese for their kindness, because that relationship means equal footing. Even if one mouse has more than the other all the time, the mouse with very little cheese can still break off a crumble here and there to share with its giving mouse friends.
Sometimes I meet a mouse who wants me to just take all its cheese and never give any back. They say, "Would you like some cheese?" and I may say, "Oh, how delicious. I'm getting more cheese tomorrow that we can also share."
A good mouse will usually accept sharing your cheese later. You may not have much, but you only need to share a little to show your appreciation for mouse friends.
If the mouse says, "No, no, keep your cheese. I just want you to have some of mine" and they are not a mouse you have a history of sharing freely with, there's a good chance they're a rat! And rats, like the witches of gingerbread houses, only want you to eat all their cheese toucan swallow to fix you right to eat.
Don't let the rats consume you. Share cheese like friends--mutually.
